Overview

The Compu-Fire 55566 is a 40-amp, 3-phase charging system kit designed for 1999-2002 Harley-Davidson Evo models.

This kit provides 25 amps at idle and 40 amps continuously above 2800 RPM. It features a unique narrow rotor and stator combination that fits Softail/Dyna primary cases without frame modifications. The precision-balanced, vented rotor helps keep the stator cooler in closed primary systems, ensuring maximum output under high current draw conditions. The voltage regulator is calibrated to 14.25 volts from idle upwards and bolts on easily. A large flanged seal spacer offers maximum support for the rotor.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
